ugrpc::client::middlewares::log::Component Class Reference

#include <userver/ugrpc/client/middlewares/log/component.hpp>

Detailed Description

Component for gRPC client logging.

Warning

Logs are currently written with log level debug by default, which typically means that they are not written in production. See details below.

Static options:

Name	Description	Default value
log-level	log level to use for Span, status code and the facts of sending requests receiving responses arriving	debug
msg-log-level	log level to use for request and response messages themselves	debug
msg-size-log-limit	max message size to log, the rest will be truncated	512
trim-secrets	trim the secrets from logs as marked by the protobuf option	true (*)

Warning

* Trimming secrets causes a segmentation fault for messages that contain optional fields in protobuf versions prior to 3.13. You should set trim-secrets to false if this is the case for you. See https://github.com/protocolbuffers/protobuf/issues/7801

Static configuration example:

        grpc-client-logging:
            log-level: info
            msg-log-level: info
            msg-size-log-limit: 512

In this example, we enable logs for gRPC clients in production.

Member Function Documentation

GetComponentHealth()

ComponentHealth components::ComponentBase::GetComponentHealth ( ) const

inlineoverridevirtualinherited

Override this function to inform the world of the state of your component.

Warning

The function is called concurrently from multiple threads.

Reimplemented from components::RawComponentBase.

Reimplemented in server::handlers::Restart.

Definition at line 35 of file component_base.hpp.

GetMiddlewareFactory()

std::shared_ptr< const MiddlewareFactoryBase > ugrpc::client::middlewares::log::Component::GetMiddlewareFactory ( )

overridevirtual

Returns a middleware according to the component's settings.

Implements ugrpc::client::MiddlewareComponentBase.

OnAllComponentsAreStopping()

void components::ComponentBase::OnAllComponentsAreStopping ( )

inlineoverridevirtualinherited

Component may use this function to stop doing work before the stop of the components that depend on it.

Base components may override it and make final to do some work before the derived object constructor is called. Don't use it otherwise.

Reimplemented from components::RawComponentBase.

Reimplemented in urabbitmq::ConsumerComponentBase, and components::Server.

Definition at line 58 of file component_base.hpp.

OnAllComponentsLoaded()

void components::ComponentBase::OnAllComponentsLoaded ( )

inlineoverridevirtualinherited

Component may use this function to finalize registration of other components that depend on it (for example, handler components register in server component, and the latter uses OnAllComponentsLoaded() to start processing requests).

Base components may override it and make final to do some work after the derived object constructor is called. Don't use it otherwise.

Reimplemented from components::RawComponentBase.

Reimplemented in urabbitmq::ConsumerComponentBase, components::Server, and server::handlers::Ping.

Definition at line 51 of file component_base.hpp.

OnLoadingCancelled()

void components::ComponentBase::OnLoadingCancelled ( )

inlineoverridevirtualinherited

Called once if the creation of any other component failed. If the current component expects some other component to take any action with the current component, this call is a signal that such action may never happen due to components loading was cancelled. Application components might not want to override it.

Reimplemented from components::RawComponentBase.

Definition at line 42 of file component_base.hpp.
